Male homosexual behaviour is not simply either "active" or "passive", since penile-anal, mouth-penile, and hand-anal sexual contact is usual for both partners, and mouth-anal contact is not infrequent. A simplified method for recording sexual behaviour--a "sexual behaviour record (SBR)"--can be of value in determining the sites to be investigated and as a basis for further epidemiological questioning. Mouth-anal contact is the reason for the relatively high incidence of diseases caused by bowel pathogens in male homosexuals. Trauma may encourage the entry of micro-organisms and thus lead to primary syphilitic lesions occurring in the anogenital area. Similarly, granuloma inguinale, condylomata acuminata, and amoebiasis may be spread from the bowel of the passive homosexual contact. In addition to sodomy, trauma may be caused by foreign bodies, including stimulators of various kinds, penile adornments, and prostheses.
男性同性恋行为并非简单地分为“主动”或“被动”，因为阴茎-肛门、口-阴茎和手-肛门性接触对双方来说都很常见，口-肛门接触也并不罕见。一种记录性行为的简化方法——“性行为记录（SBR）”——在确定要调查的部位以及作为进一步流行病学询问的基础方面可能具有价值。口-肛门接触是男性同性恋者中肠道病原体引起的疾病发病率相对较高的原因。创伤可能会促使微生物进入，从而导致肛门生殖器区域出现原发性梅毒病变。同样，腹股沟肉芽肿、尖锐湿疣和阿米巴病可能会从被动同性恋接触者的肠道传播。除了鸡奸，创伤还可能由异物引起，包括各种刺激器、阴茎装饰品和假体。
